5.3 STABLE for production server?

[PawelG]

 Hello,

 I've been using 4.X branch for production servers. Yesterday I bought
 box in datacenter with RAID 1 controller and operators in DC set up FreeBSD
 5.X for me (instead 4.X i asked) because they have troubles with set
 up RAID controller runing on 4.X.

 I have two options:
 
 Posting with Datacenter and try to convince them to make RAID 1
 running on 4.X (I found on freebsd-hardware list that 3ware 7006-2
 controller runing fine).

 or
 
 Runing production server (Apache, Mysql, Postfix + ATA RAID 1) on 5.X.

 I would like to know your opinion about 5.3-STABLE for this
 pourpose. I googled some and found that it isn't good idea but all
 those opinions was pretty old (related for ex. to older BETA version
 of 5.X branch)

 kind regards,
